IMPRovED Woon PAVEMENT.

The Schedulg refen'd to in these Letters Patent and making part of the same.

To all whom it may concern..-

Be it known that I, ANTOINE It. MCNAIR, ofthe city, county, and State of' New York, have invented a new and useful Improvement in Vooden Pavements for streets and other thoroughfares; and do hereby declare that the following` is a general description thereof, reference being had to the accompanying drawings, making part of this specification, of which- Figure l represents a perspective view of a portion of a wooden pavement constructed in accordance with my invention; l

Figure 2, a longitudinal, and

Figure 3, a transverse section of same.

y Figures 4 and 6 are views of a wooden paving-block as removed from the. pavement, and

Figure 5, a view of one of the block-supporters.

This invention, relating to animprovement inwooden pavements, I construct in the following manner, viz:

In the iiist place, I lay an open frame-work of wood on a bed of concrete,- sand, or clay, filling in with and tamping the said concrete, sand, or clay firmly, so as to form a hard and even surface with the upper surface ofthe open frame-work. I next lay on and transverselyof` said frame work, a supporting-piece or bridge, having shoulderston which the paving blocks,-

having corresponding recesses, rest, and I fasten the paving-blocks to the supporting-piece, by wooden treenails, driven horizontally, and so on, alternately laying a support-piece and a row of paving-blocks, breaking joints in the laying of the blocks, and at intervals `I fasten the paving, so constructed, to the frame, by

impervious to the elements, and in which ironor other coiroding substance is dispensed with. In the drawings- A indicates the concrete, sand, or clay foundation.

B, the ties. v

O, the' stretcher-s laid on theI ties, and fastened to the same by wooden treenails d, said ties and stretchers forming the. wooden frame-work, on which are laid the wooden bridge-pieces E, which span the spaces between and over the stretchers C. 1

These bridges are formed with chamfered shoulders j' f, for reception and support of the paving-blocks G,

which have corresponding chamfered recesses gg, which rest on the said shoulders ofthe bridges; the bridges and paving-blocks. being fastened together by wooden treenails hv h, driven horizontally into bridges and paving-blocks, as .shown particularly in fig. 2, and the said paving-blocksare, at intervals, fastened to the stretchers, by treenails t', driven vertically into the blocks and stretchers,

The bridges do not :extend up to the surface of the paving, for the purpose of leaving a groove, k, or foothold `for draught-animals, and at the intersection of streets, the paving-blocks may be so prepared as to leave a similar buttransverse recess forsaid purpose.

This pavement-.may be prepared at the workshop in sections of convenient size, (see fig. 1,) and laid on the 'streets with rapidity, causing very little interruption to trac, and forms a substantial and yet sufciently elastic roadway, and is easily repaired.

I disclaim shouldered paving-blocks resting on supports, and the joining of them to said supports by treenails.

Vhat I claim as my invention, and desire to secure Witnesses:

ARTHUR NEILL, ARTHUR B. WILLIAMS.
